Key Stage 3
Meaning
Kilo is a Unit Prefix that means a number is 1000 times bigger than the normal unit.
About Kilos
- Kilo can be shortened to a lower case k.
Examples
- A kilometre (km) is 1000 metres (m).
- A kilovolt (kV) is 1000 volts (V).
- A kilogram (kg) is 1000 grams (g).
Converting from kilos
To convert from kilo to the base unit you must times by 1000. \[5km = 5 \times 1000m = 5000m\] \[12kA = 12\times1000A = 12000A\] \[3.4kV = 3.4\times1000V = 3400V\] \[0.53kN = 0.53\times1000N = 530N\] \[0.082kJ = 0.082\times1000J = 82J\]
Converting to kilos
To convert to kilo from a base unit you must divide by 1000. \[23000m = \frac{23000}{1000}km = 23km\] \[8200A = \frac{8200}{1000}kA = 8.2kA\] \[670V = \frac{670}{1000}kV = 0.67kV\] \[32N = \frac{32}{1000}kN = 0.032kN\] \[2J = \frac{2}{1000}kJ = 0.002kJ\]
Key Stage 4
Meaning
Kilo is a Unit Prefix that means a number is 103 times bigger than the normal unit.
About Kilos
- Kilo can be shortened to a lower case k.
Examples
- A kilometre (km) is 103 metres (m).
- A kilovolt (kV) is 103 volts (V).
- A kilogram (kg) is 103 grams (g).
Converting from kilos
To convert from kilo to the base unit you must times by 103. \[5km = 5 \times 10^3m = 5000m\] \[12kA = 12\times 10^3A = 12000A\] \[3.4kV = 3.4\times 10^3V = 3400V\] \[0.53kN = 0.53\times 10^3N = 530N\] \[0.082kJ = 0.082\times 10^3J = 82J\]
Converting to kilos
To convert to kilo from a base unit you must divide by 103. \[23000m = \frac{23000}{10^3}km = 23km\] \[8200A = \frac{8200}{10^3}kA = 8.2kA\] \[670V = \frac{670}{10^3}kV = 0.67kV\] \[32N = \frac{32}{10^3}kN = 0.032kN\] \[2J = \frac{2}{10^3}kJ = 0.002kJ\]
